3. General instructions

3.1 General rules

The installation of an oil burner should be carried out in accordance with

local regulations. The installer of the burner must therefore be aware of all

regulations relating to oil and combustion.

Only oil suitable for the burner should be used and then in combination with

a suitable oil ﬁlter before the oil pump of the burner.

If the burner is replacing an existing burner make sure that the oil ﬁlter

is replaced or cleaned. The installation must only be undertaken by

experienced personnel. Care should be taken by the installer to ensure

that no electrical cables or fuel/gas pipes are trapped or damaged during

installation or service/maintenance.

3.1.1 Installation and maintenance instructions

The maintenance instructions supplied with the burner must be kept at an

easily accessible location in the boiler room.

3.1.2 Instructions

The user must be receive detailed instructions concerning the functionality

of the oil burner and entire system. It is the responsibility of the supplier to

provide the user with instructions.

3.1.3 Inspection and maintenance

The boiler/burner should be examined regularly for any signs of malfunction

or oil leakage. (See service schedule)

3.1.4 Start up

In order to obtain the correct setting, a ﬂue gas analysis and temperature

measurement must be carried out. Otherwise, there is a risk of soot build

up, poor efﬁciency or condensation precipitation in the chimney. The system

must be ﬁne-tuned at start-up. The temperature in the chimney must be at

least 60 °C at 0.5 m down in the chimney to prevent condensation.

4.1 Handling and lifting instruktion

!The lifting aid are available

as spare parts.

16 Bentone

4.2 Acceptance inspection

Make sure everything is delivered and the goods have not been damaged

during transit. If something is wrong with the delivery, report it to the supplier.

Transport damage must be reported to the shipping company.

4.3 Preparations for installation

Check that the burner’s dimensions and capacity range are suitable for the

boiler in question. The power data on the type sign refers to the burner’s min.

and max. power.

4.4 Distribution of oil

In order to achieve good reliability, it is important that the oil distribution

system is designed correctly.

Take the following into account:

• Selection of pipe diameter, pipe length and height difference; see

Pump instruction.

• Pipelines are to be laid with a minimal number of glands.

• The pipes are to be laid so that the oil supply hoses are not subjected

to tensile stresses or are excessively bent when the burner is swung

out or removed for service.

• The oil ﬁlter should be installed so that the ﬁlter cartridge can easily be

replaced or cleaned. Self-cleaning ﬁlters are recommended for oils of a

higher viscosity or oils that contain signiﬁcant impurities.

• Oil-affected parts shall be selected in materials that are capable of

withstanding the medium’s physical properties.

• When installing oil hoses, check that the inlet and return hoses are

ﬁtted to the appropriate connection on the oil pump. The hoses shall

be located so that they do not bend or become subject to tensile load.

• Bleed the oil system. The oil pump/oil preheater may be damaged if

run dry. The vacuum should not fall below 0.3 bar in the suction line

during start-up.

!Be sure to ﬁll the

burner oil system

before starting it for

the ﬁrst time.

!If any electrical connection is used other than that recommended by Bentone,

there may be a danger of damage to property and personal injury.

4.5 Electrical connection

• Before work on the electrical connection, the current should be

disconnected so that the installation is isolated.

• Electrical connection must be done in accordance with the applicable

regulations.

• Burners should be connected to an isolator switch.

• The connection should be made in accordance with the wiring

diagram.

• Fuse rating is as required.

!The oil ﬁlter must

be installed before

the burner’s oil

pump.

4.6 Mount the burner on the boiler

1. Separate the burner body and the ﬂ ange.

2. Remove the brake disc from the oil pipe.

3. Install the selected nozzle, (see Technical data).

4. Install the brake disc on the oil pipe

5. Remove the burner pipe from the ﬂ ange.

6. Install the ﬂ ange with gasket on the boiler.

7. Install the burner pipe on the ﬂ ange. Make sure that the holes in the

front edge of the burner pipe are pointing down (not on all burner

pipes). This allows any drops of oil to run out.

8. Insulate between the burner and boiler door to reduce radiated heat.

9. Install the burner body on the ﬂ ange.

10. Lock the burner body using with the nut/nuts.

11. Connect the oil pipes to the pump, refer to the chapter - servicing of

burners.

12. Connect the burner electrically, refer to the chapter - servicing of

burners.

!If the burner tube must be installed from the inside

of the boiler, this means that the boiler must be

opened or have a spectacle ﬂ ange that is desig-

ned so that it can be reconnected with the burner

tube mounted.

4.7 Check oil line seals

Once the burner has been installed and commissioned, the seals of the

various coupling elements should be checked (A).

When a leak is detected, it is usually sufﬁ cient to tighten the coupling element

that is leaking.

Burner output 400kW

Estimated nozzle output 400 kW/11,86 kWh/kg*= 33,8 kg/h

Nozzle selection in accordance with the table. (See technical data) Nozzle

selection is based on the selected pump pressure and the desired effect.

According to the nozzle table, this provides the following nozzle.

Selected pump

pressure

10,0 bar

Nozzle 9,00 gph 9,00 gph distributed to two nozzles,

e.g. 6.0 gph at stage-1 and 3,0 gph at

stage-2

Basic settings should only be seen as setting values to get burner to start

and establish a ﬂame. Once the burner has started and established a ﬂame,

it will be necessary to adjust the settings so that they are adapted to the

installation in question and the fuel used at the time.

Basic settings

The setting value for 400 kW in accordance with basic setting tables. For the

correct procedure when implementing settings, see below Nozzle assembly

control, brake plate B 45-2. Air setting see below.

4.8 Examples of basic setting B 45 2.2

Nozzle B 45-2

Burner output 400 kW

400 / 11,86 = 33,8 kg/h 10bar

According to the nozzle table, this provides the following nozzle.

Step 1 6,00 Gph = 265kW

Step 2 3,00 Gph = 132kW

Basic setting B 45-2

The values are available in the tables for setting values of inserts or air

dampers.

Insert 400kW = 22

Low load air damper, orange =55°

MV2 Open, black =65°

Air damper step 2, red =80°

These are the default settings and controlling the combustion will take place

during operation.

Selection of power and connection between the different power stages must

be selected and adjusted so that the system achieves good functionality.

Setting of brake disc and air ﬂow

Prior to commissioning, the basic settings of the burner can be set in

accordance with the diagram. See under Basic settings Note that it is simply

a matter of a basic setting that should be adjusted retrospectively once

the burner has started. A ﬂue gas analysis and soot quantity measurement

must be carried out when ﬁne-tuning the burner.
